This is a digital stepper drive implemented with Leadshine’s advanced stepper control technology. It is easy to use and it can be used to drive 2-phase and 4-phase motors(from Nema 8 ~ Nema 17 size) smoothly with less heat and noise. It works with 18-30VDC voltage and can provide max 2.2A peak current. You can set the DIP switches to get the current and microsteps you need.
